evo.com | SRAM Chains > The recommended chain for SRAM GX drivetrains, the SRAM PC-1130 11-Speed Chain features a nickel silver and chrome hardened finish, a PowerLock(R) closing link for tool free and consistent chain repair and PowerChain II tech for increased rivet strength and load shifting performance. Strong, Precise and Lightweight Nickel Silver-Treated Outer Plate PowerLock(R) SRAM chain engineers developed PowerLock(R) as a tool free, sure, and consistent way to connect their chains. While PowerLock(R) does not require special tools for install, the especially tight tolerances of 10-, 11- and 12-speed drivetrains mandate that each PowerLock(R) is good for a one-time application only. Chrome Hardened Pins PowerChain II Extremely strong. Incredibly precise. SRAM's PowerChain II increases front and load shifting performance without sacrificing rear shifting precision. The Step2(TM) riveting process increases the Push Pin Power for increased strength and durability. | SRAM PC-1130 11spd Chain 2023 - 120 Links
